Hello all. I am considering using an air eraser to give a flute body a satin style finish. It is solid silver with plating. I just have a few queries. Firstly, if I lightly mark the surface to give it a textured effect, would it require to be refinished over that in some fashion (replating/clear liquid finish)? Secondly, would it be unwise to do this effect over the tone holes? Would I be better served to leave them as they are? I am just in the speculating stage at the moment. It is not a wonderful flute, but I wouldn't want to wreck it either. Thanks for your time.
